Hi, I'm Jean-Jeffrey Marcellus, DNP, PMHNP-BC, AGNP-BC, a board-certified Psychiatric Mental Health Nurse Practitioner with over 19 years of healthcare experience. I provide compassionate, evidence-based care for adults experiencing ADHD, anxiety, depression, insomnia, and substance use disorders.

I specialize in Medication-Assisted Treatment (MAT) for alcohol, opioid, benzodiazepine, kratom, and prescription medication dependence. My approach is collaborative and personalized, focusing on creating treatment plans that support each individual's goals, recovery, and overall well-being.

I offer both in-person and telehealth appointments, providing a welcoming, judgment-free environment where patients feel heard, respected, and empowered. I am committed to delivering culturally responsive care and making high-quality mental health services accessible to individuals from diverse backgrounds.

I’ve been helping people for over 20 years as a Licensed Clinical Social Worker, and I’m so proud of you for taking this important step toward caring for yourself. It’s not always easy, and it shows strength and courage.

Throughout my career, I’ve worked with individuals of all ages and backgrounds, addressing a wide range of challenges. My experience includes school settings, college multicultural affairs, outpatient drug and alcohol treatment, and mental health counseling.

I also spent nine years in a hospital setting, working in psychiatric emergency services and on adolescent and adult inpatient units. This gave me extensive experience in crisis intervention and in supporting people through both mild and severe mental health concerns. Today, I continue to work in outpatient mental health, helping clients navigate life’s challenges and build resilience.

My goal is to provide a safe, supportive space where you feel heard and understood. Together, we’ll work toward the changes you want to see in your life. I look forward to working with you.

I believe prioritizing mental health is key to stability in life. I know there is a better world out there and people need the tools to connect with their upmost insight for mental well being. In this field I am always eager to research and find healing processes to tailor the need of each individual.

My name is Caitlin Clouse. Licensed Clinical Social Worker is just one of the many titles I carry. First and foremost I am a mom, wife and daughter. Through my own lived experiences—including an estranged relationship with a parent during childhood, as well as experiencing secure attachment within a strong and supportive family system—I witnessed firsthand the impact that difficult and unhealthy relationships can have on an individual’s emotional regulation and overall well-being. I also experienced how supportive relationships and co-regulation within a family system can foster resilience, confidence, and motivation.

These experiences is what led to my decision to attend Adelphi's MSW program. I have always had a passion to work with adolescents to help them feel understood and validated.

I began my career providing in-home support to children and families experiencing crisis. Through this work, I developed a strong foundation in supporting individuals and families through challenging circumstances and transitions. Through my practice in building positive relationships with adolescents, I have been able to assist them in organizing their thoughts and communicating them more effectively to their family and friends. I have been able to see first hand how treating them with dignity and respect allows them to grow their perspectives and become better listeners, which enhanced the family system as whole. No matter the current dynamics of one's family, we all come from one, which is why utilizing Structural Family Therapy and ACT has been helpful in my practice with not just families but individuals as well. Whether you're a parent, daughter, son, brother or sister, I'm here to help.

Reaching out is hard, especially if you've already tried therapy before and it didn't quite get you where you needed to go. I want you to know that doesn't mean something's wrong with you, it usually just means the approach wasn't the right fit. I've spent over a decade working with people carrying trauma and addiction, adults and teens both, and what I care about most is helping you feel truly understood, maybe for the first time, before we even get to the work of healing.

Therapy is a collaborative process, and a strong therapeutic relationship is key to meaningful progress and lasting change. My approach is grounded in a strengths-based, client-centered perspective that supports each person’s capacity for growth and self-understanding. I strive to create a supportive, compassionate, and nonjudgmental space where you can openly explore your thoughts, emotions, and experiences at a pace that feels comfortable for you. Whether you are navigating life transitions, managing stress, or seeking greater self-awareness, therapy can provide a space for reflection, healing, and meaningful change.
